Existential Sentences: 있다 / 없다 (N이/가 있다) | Korean Grammar

English hands you one verb, to be, for jobs that Korean keeps strictly apart. "I am a student," "there is a book," and "the book is on the desk" all use is in English — but Korean uses two completely different words. Identity ("A is B") is the copula 이다. Existence and presence ("there is," "is located," even "have") is the verb 있다 — and its negative is not "not 있다" but the separate word 없다. Getting this split right on day one prevents one of the most stubborn beginner errors: reaching for 이다 to say "there is."

The frame: N이/가 있다 / 없다

To say something exists or is present, mark it with the subject particle 이/가 and end with 있다 ("exists / there is") or 없다 ("does not exist / there isn't"). In polite speech that is 있어요 / 없어요.

질문이 있어요?

jilmuni isseoyo?

Do you have a question? / Is there a question?

돈이 없어요.

doni eopseoyo

There's no money. / I don't have money.

시간이 없어요.

sigani eopseoyo

There's no time.

Note that 없다 is its own word, not a negated 있다. Korean does not say ×안 있다 for "there isn't"; the negative of 있다 is the suppletive 없다, the way English "good" has the suppletive "bad" rather than "ungood." This pairing — 있다 / 없다 — is one of the first things to memorize as a unit.

Location with 에

To say "there is X at/in/on Y," mark the place with the locative particle 에 and keep the existing thing on 이/가.

교실에 학생이 있어요.

gyosire haksaeng-i isseoyo

There are students in the classroom.

냉장고에 우유가 있어요.

naengjanggo-e uyuga isseoyo

There's milk in the fridge.

The template is [place]에 [thing]이/가 있어요. The 에 is doing the work of English "in / on / at," and dropping it is a common early mistake — 냉장고 우유가 있어요 leaves the fridge floating with no relation to the milk.

여기 있어요.

yeogi isseoyo

Here it is. / It's here.

The same frame means "have"

Korean does not have a dedicated verb for "to have." Instead it says, in effect, "X exists (to me)" — the identical 있다 frame. So 있어요 does double duty: "there is" and "I have," disambiguated only by context.

저는 시간이 있어요.

jeoneun sigani isseoyo

I have time. (lit. as for me, time exists)

책이 있어요.

chaegi isseoyo

There's a book. / I have a book.

This is why 질문이 있어요? translates equally as "Is there a question?" or "Do you have a question?" The possessor, when named, becomes a topic (저는…), and the thing possessed stays on 이/가 — a double-marking pattern that gets its own treatment on the possession page.

💡

Split the English "is" before you translate. Identity ("A is B") → 이다 (저는 학생이에요). Existence, location, or possession ("there is," "is at," "have") → 있다 / 없다 (책이 있어요). Sorting this once, up front, kills a whole family of errors.

있다 is a verb, and behaves like one

Because 있다 is a real verb (not a copula), it conjugates through the full tense system and even takes verb-style attributive endings — something the copula and adjectives do differently.

Form	Korean	Meaning
Present	있어요	there is / have
Past	있었어요	there was / had
Future / conjecture	있을 거예요	there will be / probably is
Attributive	있는	that exists / that (someone) has

어제는 시간이 있었어요.

eojeneun sigani isseosseoyo

Yesterday I had time.

내일은 시간이 있을 거예요.

naeireun sigani isseul geoyeyo

I'll have time tomorrow.

Crucially, 있다 takes the verb-style attributive -는 (있는, 맛있는), not the adjective-style -은. So "a restaurant that's good" is 맛있는 식당, and "a person who has money" is 돈이 있는 사람.

여기 맛있는 식당이 있어요.

yeogi masinneun sikdang-i isseoyo

There's a good restaurant here.

The reframe: three verbs hiding inside English "is"

English to be conflates three relationships that Korean keeps in separate boxes:

English	Relationship	Korean
I am a student.	identity / equation	저는 학생이에요 (이다)
There is a book.	existence	책이 있어요 (있다)
The book is on the desk.	location	책이 책상에 있어요 (있다)

So "there is a book" is 책이 있어요 — never ×책이 예요 or ×책이다, which would try to say the impossible "a book is [equals]…". The moment your English sentence means "exists," "is located," or "has," your Korean verb must be 있다 (or 없다), full stop. Reserve 이다 for the narrow case where you could rephrase the English with "equals": I am a student = I equal (a) student.

Common Mistakes

Mistake 1 — Using 이다 for "there is / are." The single biggest error: a copula where existence is meant.

❌ 방에 침대가 이에요.

Not a sentence — existence needs 있다, not the copula.

✅ 방에 침대가 있어요.

bang-e chimdaega isseoyo

There's a bed in the room.

Mistake 2 — Omitting the locative 에. The place needs 에 to attach to the sentence.

❌ 냉장고 우유가 있어요.

Awkward — with no 에, the fridge has no grammatical link to the milk.

✅ 냉장고에 우유가 있어요.

naengjanggo-e uyuga isseoyo

There's milk in the fridge.

Mistake 3 — Negating 있다 with 안. "There isn't" is the suppletive 없다, not ×안 있다.

❌ 시간이 안 있어요.

Wrong — the negative of 있다 is the separate word 없다.

✅ 시간이 없어요.

sigani eopseoyo

There's no time. / I don't have time.

Mistake 4 — Using the copula to say "I have." "Have" is existence (있다), not identity (이다).

❌ 저는 차가 예요.

Not a sentence — 'I have a car' is existence, so 있어요, not 예요.

✅ 저는 차가 있어요.

jeoneun chaga isseoyo

I have a car.

Key Takeaways

Existence, location, and possession use 있다 / 없다 — never the copula 이다. The frame is N이/가 있다/없다.
없다 is a separate word, the suppletive negative of 있다; there is no ×안 있다.
Location adds the locative 에: [place]에 [thing]이/가 있어요.
The same frame means "have" (책이 있어요 = "there's a book" or "I have a book").
있다 is a true verb: it takes full tenses (있었어요, 있을 거예요) and the verb-style attributive -는 (있는, 맛있는).
